I actually pictured Confuse differently myself as sort of an upgraded form of paralyze.
Confuse: Monster has a X% chance of being countered every attack.
(x% obviously varies on your Mnd/Int vs mobs Mnd/Int)

Either way if SE does decide to make us a true enfeebler they HAVE to give us a way to actually reduce damage from a monsters TP attacks (besides Bio). Sure Slow somewhat does that, but let's be honest, compared to how fast a monster gains TP from players hitting a monster reducing the monsters attack speed hardly affects its WS frequency.
I mean look at our 3 main enfeebles. Paralyze, Slow, and Blind(sort of). NONE of these reduce TP damage in the slightest except for maybe blind for a physical TP, but then again if you have a tank that can actually evade it'll probably be a ninja that has an enfeeble JUST as powerful as Blind II (unless you saboteur it). All these really do is reduce the monsters DoT damage and when is a monster's DoT really a threat. 99% of the time it's the TP moves that are going to be the issue and Red mage doesn't have a single viable way of stopping those. So yeah, sure we are the masters of damage reduction enfeebles, but that really doesn't say much when we can't even reduce the damage from the most dangerous part of the fight.
